Abstract
Valuable leafy green vegetable kale/Brassica oleracea var. Sabellica L. also known as a curly cabbage, firstly was introduced in Armenia, and its high productivity and prospectively were studied and established in water steam hydroponics experimental modules (gully, cylindrical and continuous), classical hydroponics, as well as in soil culture. In kale revised from hydroponically different systems the raw material and the output of pharmaceutical indices (vitamin C, extractive substances, flavonoids and tannins) are higher 1.5-1.8 times and 1.2-2.3 times, respectively, compared with soil culture. Water stream hydroponics is safer radio-ecological, biotechnological method for production of raw material than classical hydroponics and soil culture.
